Literacy and Technology?
Collaborative writing is an essential skill as group projects become more common in the workplace. By providing students with the opportunity and experience in collaborative writing projects, teachers can not only help students learn from one another but also help students develop necessary skills in teamwork and cooperation. Collaborative writing is difficult to achieve without the use of technologies such as wikis, blogs, Google Docs, or another similar tool for helping students collaborate on an assignment. MixedInk is another Web 2.0 tool which allows students the opportunity to share information and collaborate. However, MixedInk differs from wikis, blogs, and Google Docs in several ways, including authorship and and drafting. While traditionally difficult to track in most collaborative writing tools, authorship in MixedInk is tracked automatically and color-coded. MixedInk also enables an unlimited number of users to collaborate on a task at once, rather than only allowing a single user to to edit at a time. Drafting is not confined to a single document. MixedInk displays every user's work rather than simply displaying the most recent editor's work, allowing user's to draw ideas from a multitude of revisions no matter what stage of the drafting process.
MixedInk provides a fresh look at collaborative writing. Not only are students able to submit their own drafts, but they are able to draw upon the writing of their group members to create one cohesive piece. MixedInk is a great tool for teaching about collaboration and use of secondary sources. Through the automatic color-coded authorship feature, students learn about analyzing ideas and ethically incorporating another person's ideas with their own, thus teaching students about the concept of plagiarism and giving credit to appropriate authors. This would be a great tool to explore in the classroom and help innovate the instruction of literacy.
